IXYS UK Westcode announces higher ratings for W2624 and introduce a new package option
IXYS UK Westcode announces an increased maximum voltage and a new low profile package option for its W2624 series rectifier diode. The maximum grade voltage is increased to 2.8Kv and a new 21mm thick package option is added to the standard range for this rectifier diode.
IXYS UK is continuing to optimise its rectifier diode portfolio and has this month announced the increased maximum voltage rating for its W2624 series diode from 2.5kV to 2.8kV. IXYS UK have managed to increase the voltage without compromising the average current rating which remains at 2624A at a heat sink temperature of 55°C. The diode has a surge rating of 30.8Ka and a maximum junction temperature of 160°C.
The device compromises a 50mm diameter silicon die bonded onto a metal disc packaged in an industry standard outline, fully hermetic ceramic package with 47mm diameter nickel plated copper electrodes. As well as the established 26mm thick package the diode is now also offered in a slim line 21mm thick package; this thinner outline is compatible with some older outlines which are no longer available from the original manufacturers.
The IXYS device is available in two voltage classes and the two package thicknesses outline above. Part number designations for the expanded range of rectifier diodes are: for the thicker 26mm package, W2624NC240 for a 2400V part and W2624NC280 for a 2800V part; for the new 21mm thick package W2624ND240 for a 2400V part and W2624ND280 for a 2800V part. If required the diodes can be supplied selected for parallel operation against a customer specific specification, consult factory for details.
Typical applications for this device include: track side rectifiers for DC operated light rail systems, rectifiers for DC locomotives, front end rectifiers and bridges for industrial applications, DC power supplies, utilities and chemical power supplies.
